We look at the division of 84140234 by 2 
We want to figure out the number of times 84140234 can be divided by 2.

Advancing to step 1:
2 goes into 8 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Advancing to step 2:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Going ahead to step 3:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 420.0
Subtract 0 from 1 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Going ahead to step 4:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 4207.0
If we take 14 away from 14, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Going ahead to step 5:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42070.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Advancing to step 6:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 420701.0
If we subtract 2 from 2, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

On to step 7:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 4207011.0
The remainder is 1 after subtracting 2 from 3.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Advancing to step 8:
14 divided by 2 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 42070117.0
Subtracting 14 from 14 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 42070117.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42070117.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 42070117.0 with a remainder of 0.0.
